CWE-12: ASP.NET Misconfiguration: Missing Custom Error Page

MITRE CWE weakness

Description

An ASP .NET application must enable custom error pages in order to prevent attackers from mining information from the framework's built-in responses.

Common consequences

• Confidentiality: Read Application Data

Mitigations

System Configuration — Handle exceptions appropriately in source code. ASP .NET applications should be configured to use custom error pages instead of the framework default page.

Architecture and Design — Do not attempt to process an error or attempt to mask it.

Implementation — Verify return values are correct and do not supply sensitive information about the system.
